• Impacts of the invasive round goby (Neogobius melanostomus) on benthic invertebrate fauna: a case study from the Baltic Sea 

      Van Deurs, Mikael; Moran, Nicholas P.; Plet-Hansen, Kristian Schreiber; Dinesen, Grete E.; Azour, Farivar; Carl, Henrik; Møller, Peter Daniel Rask; Behrens, Jane W (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-19)
      The round goby (Neogobius melanostomus) was first observed in the Baltic Sea in 1990 and has since displayed substantial secondary dispersal, establishing numerous dense populations where they may outcompete native fish and negatively impact prey species. There have been multiple round goby diet studies from both the Baltic Sea and the North American Great Lakes where they are similarly invasive. ...
    • A National Scale “BioBlitz” Using Citizen Science and eDNA Metabarcoding for Monitoring Coastal Marine Fish 

      Agersnap, Sune; Sigsgaard, Eva Egelyng; Jensen, Mads Reinholdt; Ávila, Marcelo De Paula; Carl, Henrik; Møller, Peter Rask; Krøs, Simon Leed; Knudsen, Steen Wilhelm; Wisz, Mary S.; Thomsen, Philip Francis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-28)
      Marine biodiversity is threatened by human activities. To understand the changes happening in aquatic ecosystems and to inform management, detailed, synoptic monitoring of biodiversity across large spatial extents is needed. Such monitoring is challenging due to the time, cost, and specialized skills that this typically requires. In an unprecedented study, we combined citizen science with eDNA ...
    • Short-term temporal variation of coastal marine eDNA 

      Jensen, Mads Reinholdt; Sigsgaard, Eva Egelyng; Ávila, Marcelo De Paula; Agersnap, Sune; Brenner-Larsen, William; Sengupta, Mita Eva; Xing, Yingchun; Krag, Marcus Anders; Knudsen, Steen Wilhelm; Carl, Henrik; Møller, Peter Daniel Rask; Thomsen, Philip Francis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-23)
      Temporal variation in eDNA signals is increasingly explored for understanding community ecology in aquatic habitats. Seasonal changes have been addressed using eDNA sampling, but very little is known regarding short-term temporal variation that spans hours to days. To address this, we filtered marine water samples from a single coastal site in Denmark every hour for 32 h. We used metabarcoding to ...
    • Uncovering neutral and adaptive genomic differentiation among European perch with brackish water and freshwater origin in the western Baltic Sea region 

      Skovrind, Mikkel; Pacheco, George; Christensen, Emil Aputsiaq Flindt; Gopalakrishnan, Shyam; Fietz, Katharina; Holm-Hansen, Tore Hejl; Vieira, Filipe Garrett; Krag, Marcus Anders; Carl, Henrik; Gilbert, Marcus Thomas Pius; Olsen, Morten Tange; Møller, Peter Daniel Rask (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-13)
      Environmental variation across the range of wild species can lead to local adaptations. The Baltic Sea was formed when the Fenno-Scandian ice sheet retreated around 12 thousand years ago, creating a new brackish water habitat colonised by both marine and freshwater fish species. The European perch (Perca fluviatilis) is a predatory freshwater fish with a large geographical distribution across ...
